2. ILC as a Global Project
R&D for a future e+e- linear collider was started more then 20 years ago in three regions.
By early 2000’s , it became a consensus among the world HEP community that an e+e- linear collider with the CM energy of about 500 GeV should be the next collider beyond the LHC.
ICFA chose the cold technology for LC as a global project, and set up a global team (GDE) for design and coordination of R&D for the ILC.

3. TDR completed: The LCC succeeded the GDE
After eight years of works, the TDR of the ILC was published in June 2013 under the leadership of the GDE Director, Barry Barish.
ICFA set up the Linear Collider Collaboration headed by Lyn Evans.

7. ILC efforts in Japan
In October 2012, after the discovery of a Higgs –like particle, the Japanese HEP community proposed a phased execution of the ILC hosted in Japan as a global project.
